SOLE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 331,926, dated December8, 1885.

Application filed April 3, 1885. Serial No. 161,139. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT VAN WAGEN- EN, of Boston, county of Suffolk,State of lvlassachusettshave invented an Improvement in Sole-Fasteners,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

The object of my invention is the production of a novel solefastener.

My improved sole-iastencr is composed of a strip or ribbon ofsheet metalcorrugated or indented and folded about a wire core, the projections orcorrugations of the strip engaging the leather or other material intowhich'the fastener is driven.

Figure 1 represents on an enlarged scale an indented strip or ribbon ofsheet metal with central wire core therein, part of thestrip being shownasinfolded within the strip to make solefastening material inaccordancewith my invention; Fig. 2, a cross-section of Fig. l in the dotted lineas m. Fig. 3 shows a sole-fastener detached, and Figs. 4 and 5 modifiedforms of strips.

A thin metal strip or ribbon, A, indented or corrugated in any desiredmanner, so as to present projections or an uneven surface at its outerside, has a wire, B, laid against it, and the strip or ribbon by theaction of a suitable die, and by methods well known to those conversantwith metal-working, the said strip or ribbon is bent closely about thesaid wire core, as shown at the left of Fig. l in the section Fig. 2. Asthe sole-fastening material is severed, the cutter used will sever thematcrial in usual manner, so as to leave a point, as at the left ofFigs. 1 and 3. The projections at the outside of the fastener engage theleather and act to retain the fastener in place.

The fastening material made as described may be out into lengthssuitable for fasteners in a nailing-machine for boot and shoe Work, orbe cut and made into nails to be fed into a machine separately.

In another application, Serial N 0. 161,138,

filed concurrently herewith, I have shown and claimed a solefastenercomposed of a corrugated or indented strip bent to form a cylindricalbody.

If desired, the cylindrical body representing the wire-like material tobe cut into short lengths for the production of fasteners may besubjected to a galvanizing-process, to fill any spaces left as theresult of bringing the strip of sheet-iron into cylindrical form.

I am aware that nails for solefastenings are commonly indented orserrated. I am also aware that shoe sole fastenings have been made ofsmooth or plain strips ofmetal folded about a fibrous core, and alsothat a tubular or tube-like fastener with open center and side has alsobeen used, the fastening separating as it is driven into the leather.

In accordance with my invention, the strip from which the fastener ismade is first corrugated or indented, and being done before the metal isput into nailshape, the cost of manufacture is decreased, and there isactually no waste of stock, and the indentations, added to thesheet-metal nail, make that class of nail or fastener operative andvaluable. The addition of the metallic core greatly stili'ens thefastener, and the indentations of the strip act in a measure to aid inholding the core in place.

I claim- The herein described sole fastening material, composed of awire core enveloped by an indented or corrugated metallic strip, allsubstantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
